Urethane acrylates for high-performance coatings

Urethane acrylates are binders with a lot of versatility for UV crosslinking systems. Abrasion resistance, scratch resistance und impact strength, gloss, chemical resistance etc. can be finetuned exactly by suitable combination of flexible and hard products. Bayer MaterialScience offers a comprehensive range of raw materials for that purpose.

A selection of urethane acrylates:

	Solids content %	Viscosity mPas 23°C	Application
Desmolux® U 100	100	7500	For plastic coatings, furniture and parquet flooring, particularly good chemical & mechanical resistance, flexible, good wear resistance
Desmolux® U 200	100	8000	For parquet flooring, heavy duty wood coatings, good chemical & mechanical resistance, flexible, good abrasion resistance
Desmolux® U 500 (formerly: VP LS 2614)	100	6000	Good abrasion and scratch resistance, particularly for parquet flooring, cork coating, film coating, tough but flexible, aromatic urethane acrylate
Desmolux® U 680 H (formerly: VP LS 2308)	80 in HDDA	29000	Particularly suitable for outdoor applications, hard, very good resistance
Desmolux® XP 2587	100	1500	For high-gloss coatings with good chemical and scratch resistance, hard, water-thinnable
Desmolux® XP 2738	100	30000	Weather-stable, good resistance to chemicals and mechanical stresses
Desmolux® XP 2740	100	8000	Weather-sable, increases the flexibility of UV coatings for outdoor applications
